The injured went sent to nearby hospitals while police closed nearby roads.

With authorities on high alert for so-called “spoiler” attacks by armed actors opposing an ongoing peace process with Marxist FARC guerrillas, President Juan Manuel Santos said on Twitter he immediately had ordered National Police director Jorge Hernando Nieto to personally take charge of the investigation.

Bogota has seen several bomb attacks over the past few years, but never targeting a location as crowded as the Andino mall on a Saturday afternoon.

ELN guerrillas have been carrying out bomb attacks in the city for decades, but due to the peace process the chance of so-called “spoiler attacks” to destabilize the country’s peace process would not be impossible

Such attack would mark an sudden new phase of Colombia’s peace process that had already gone in overdrive after smaller “spoiler” incidents, but in the countryside, not one of the most exclusive areas in Bogota that would guarantee major headlines and send a shock wave through the entire country.

Several social leaders have been assassinated since peace was signed on December 1 last year.

In some of these cases, these assassinations appeared spoiler attacks meant to destabilize the process.

Until Saturday, Colombia’s cities for years have noticed little from either the armed conflict or the peace process with the FARC, the country’s oldest and largest guerrilla group that earlier Saturday vowed to be disarmed by Tuesday.
